Individual criminal cases are not Sharia law being implemented in towns.
You can find similar domestic cases with the Amish, for example, or Hasidic Jews here in New York. With both communities, such abuse is rarely reported.
With the Amish, these 'domestic' cases go as far as repeated sexual abuse, which law enforcement and the courts tend to ignore, considering them to be internal matters to be handled by the community, whose approach tends to be having the guilty confess in front of the congregation and promising not to rape again, which of course tends to be a promise they don't have an overwhelming tendency to keep.
Basically, Amish, Hasidim, and conservative/traditionalist Muslims are the same thing, the only thing different is the shape of their headwear and the prayers they use during worship services.
